Heart Urchin belongs to class

Options

A. Asteroidea
B. Ophiuroidea
C. Echinoidea
D. Holothuroidea.

Answer

To determine the class to which the Heart Urchin belongs, we can follow these steps:

### Step 1: Identify the Options
We have four options to consider:
1. Asteroidea
2. Ophiuroidea
3. Kynordia
4. Holothuroidea

### Step 2: Analyze Each Option
- **Asteroidea**: This class includes star-shaped organisms, commonly known as starfish. Since Heart Urchins are not star-shaped, this option is incorrect.

- **Ophiuroidea**: This class includes brittle stars and basket stars, which are also flat and star-shaped. Heart Urchins do not belong to this class, making this option incorrect as well.

- **Kynordia**: This class is known for Heart Urchins, which are heart-shaped organisms. The scientific name for Heart Urchin is Kynocardium. Therefore, this option is likely correct.

- **Holothuroidea**: This class includes sea cucumbers, which are elongated and cylindrical in shape. Heart Urchins do not fit this description, so this option is also incorrect.

### Step 3: Conclusion
Based on the analysis, the Heart Urchin belongs to the class **Kynordia**.

### Final Answer
Heart Urchin belongs to the class **Kynordia**.
